Portable electronic device clamp

Abstract

Provided is a clamp for fastening a portable electronic device. The clamp comprises two spring biased sliding arms and a spring biased trigger member. Pushing the trigger member toward the body will move the shuttle member upward to unlock both arms for extending thereafter. In response to sandwiching the device between the arms releasing the trigger member will push the trigger member outward and the shuttle member downward respectively for locking the ridges. In a case of the device having its ports provided at one side or both sides thereof, two central, rectangular openings of the arms are adapted to allow the ports to dispose therein for causing no interference to a normal operation of the fastened device. A distance between both arms can be adjusted by sliding one arm toward or away from the other arm or sliding both arms toward or away from each other.

1. A clamp for fastening a portable electronic device comprising:
 a body comprising a front cover ( 11 ) of substantially rectangular, the front cover ( 11 ), on its back, comprising an intermediate recess ( 111 ) open to its both sides, two parallel plates ( 112 ) disposed in the recess ( 111 ), two upper, longitudinal slits ( 113 ) disposed at its both sides, two transverse first grooves ( 114 ) each disposed below the slit ( 113 ), an enlarged, transverse second groove ( 115 ) disposed between the first grooves ( 114 ) and being in communication therewith, two transverse third grooves ( 116 ) each disposed externally of the slit ( 113 ), and a transverse fourth groove ( 117 ) disposed below the first and second grooves ( 114 ,  115 ); and a rear cover dimensioned and shaped to releasably secure to the front cover; 
 two first resilient members ( 12 ) each disposed in an upper portion of the slit ( 113 ); 
 a second resilient member ( 130 ) anchored in the second groove ( 115 ); 
 a trigger member ( 13 ) comprising a finger tab ( 131 ) disposed externally of the body, a slanted slot ( 132 ) proximate the finger tab ( 131 ), a riser ( 133 ) disposed in the second groove ( 115 ), and a distal, internal oblique surface ( 134 ), wherein the slanted slot ( 132 ) is disposed proximate a joining portion of one slit ( 113 ) and the first groove ( 114 ), the second resilient member ( 130 ) is put on the trigger member ( 13 ) and has one end urged against the riser ( 133 ), and the oblique surface ( 134 ) is disposed proximate a joining portion of the other slit ( 113 ) and the first groove ( 114 ); 
 a shuttle member ( 14 ) comprising a horizontal member ( 141 ) disposed in the fourth groove ( 117 ), two vertical members ( 142 ) each disposed in a lower portion of the slit ( 113 ) for urging the first resilient member ( 12 ) upward, two notches ( 143 ) each disposed in the vertical member ( 142 ) so that the trigger member ( 13 ) is adapted to dispose across the notches ( 143 ), two slopes ( 144 ) each disposed at an upper edge of the notch ( 143 ), and two latches ( 145 ) each disposed on an underside of the vertical member ( 142 ); 
 left and right arms ( 15 ,  16 ) each comprising a clamping section ( 151 ,  161 ) extended forwardly and a transverse sliding section ( 152 ,  162 ) slidably projected from one end opening of the recess, the sliding section ( 111 ) including a plurality of parallel ridges ( 1521 ,  1621 ) on its top, an intermediate cavity ( 1523 ,  1623 ), and a transverse pin ( 1522 ,  1622 ) in the cavity ( 1523 ,  1623 ); 
 a third resilient member ( 153 ) substantially anchored in a space defined by the plates ( 112 ) and having its right portion put on one pin ( 1622 ) and its left portion put on the other pin ( 1522 ), and 
 whereby pushing the finger tab ( 131 ) toward the body will move the shuttle member ( 14 ) upward to compress the first resilient members ( 12 ), cause the latches ( 145 ) to clear the right and left ridges ( 1521 ,  1621 ), and cause the third resilient member ( 153 ) to expand for extending both the left and right arms ( 15 ,  16 ); and in response to placing the electronic device between the clamping sections and engaging therewith releasing the finger tab ( 131 ) will expand the first and second resilient members ( 12 ,  130 ) to push the trigger member ( 13 ) outward and the shuttle member ( 14 ) downward respectively for causing the latches ( 145 ) to lockingly engage with the left and right ridges ( 1521 ,  1621 ). 
 
   
   
     2. The clamp of  claim 1 , wherein each of the first, second, and third resilient member ( 12 ,  130 ,  153 ) is a compression spring. 
   
   
     3. The clamp of  claim 1 , wherein a distance between the left and right arms ( 15 ,  16 ) is adapted to adjust by sliding one of the left and right arms ( 15 ,  16 ) toward or away from the other one or sliding both the left and right arms ( 15 ,  16 ) toward or away from each other. 
   
   
     4. The clamp of  claim 1 , further comprising a pad ( 1512 ,  1612 ) protruded inwardly from an inner surface of each clamping section of the left and right arms ( 15 ,  16 ). 
   
   
     5. The clamp of  claim 1 , wherein the shuttle member ( 14 ) is of U-shaped. 
   
   
     6. The clamp of  claim 1 , wherein the rear cover ( 17 ) comprises two longitudinal ribs ( 173 ) each having an upper portion disposed in the slit ( 113 ), two spaced transverse first ribs ( 175 ) disposed in the first grooves ( 114 ) and the second groove ( 115 ), and a transverse second rib ( 172 ) disposed below the transverse first ribs ( 175 ). 
   
   
     7. The clamp of  claim 1 , wherein each clamping section comprises a central, rectangular opening ( 1511 ,  1611 ) and each of the left and right arms ( 15 ,  16 ) has a transverse, L-shaped section in its upper and lower portion respectively. 
   
   
     8. The clamp of  claim 1 , wherein the slanted slot ( 132 ) of the trigger member ( 13 ) is disposed proximate a joining portion of one of the slits ( 113 ) and the first groove ( 114 ), and the oblique surface ( 134 ) of the trigger member ( 13 ) is disposed proximate a joining portion of the other one of slits ( 113 ) and the first groove ( 114 ).
